Momentum and Impulse

What is the definition of momentum?

• Momentum is the force of gravity on an object

• Momentum is the energy stored in an object

• Momentum is the speed of an object

• Momentum is the quantity of motion of a moving body, measured as a product of its mass and velocity.

How do you calculate momentum?

• Momentum is calculated by dividing an object's mass by its velocity.

• Momentum is calculated by multiplying an object's mass by its velocity.

• Momentum is calculated by adding an object's mass and its velocity.

• Momentum is calculated by subtracting an object's mass from its velocity.

State the impulse-momentum theorem.

• The impulse applied to an object is not related to the change in momentum

• The impulse-momentum theorem only applies to stationary objects

• The impulse-momentum theorem states that momentum is not affected by impulse

• The impulse-momentum theorem states that the impulse applied to an object is equal to the change in momentum of the object.

Explain the concept of conservation of momentum.

• The conservation of momentum only applies to objects with mass

• The conservation of momentum states that the total momentum of a closed system remains constant if no external forces act on it.

• The conservation of momentum only applies to objects in motion

• The conservation of momentum only applies to objects at rest

Provide an example of an application of momentum.

• A common example of an application of momentum is in car safety features, such as airbags and seat belts, which are designed to reduce the impact force on passengers during a collision by extending the time over which the momentum change occurs.

• Mobile app development

• Cooking techniques

• Agricultural irrigation

What is the relationship between force, time, and impulse?

• Impulse = Force / Time

• Impulse = Force + Time

• Impulse = Force - Time

• Impulse = Force x Time

Discuss the significance of momentum in sports.

• Momentum in sports is only important for individual athletes, not for teams

• Momentum in sports is significant because it can give a team or athlete a psychological and physical advantage, leading to better performance and outcomes in competitions.

• Momentum in sports is insignificant and has no impact on performance

• Momentum in sports only affects the outcome of the game, not the performance of the athletes

Explain the difference between elastic and inelastic collisions in terms of momentum.

• In elastic collisions, momentum is conserved, while in inelastic collisions, momentum is not conserved.

• In elastic collisions, momentum is conserved, while in inelastic collisions, energy is conserved.

• In elastic collisions, momentum is not conserved, while in inelastic collisions, kinetic energy is not conserved.

• In elastic collisions, momentum is not conserved, while in inelastic collisions, momentum is conserved.

How does impulse affect the motion of an object?

• Impulse affects the motion of an object by changing its velocity or direction, depending on the magnitude and direction of the impulse.

• Impulse has no effect on the motion of an object

• Impulse only affects the color of the object

• Impulse causes the object to shrink in size

What is the role of momentum in collision sports like rugby or American football?

• Momentum has no impact on collision sports

• Momentum helps in reducing the impact force during collisions, thereby minimizing the risk of injuries

• Momentum only affects the outcome of the game, not the performance of the athletes

• Momentum is only important for individual athletes, not for teams
